The Series 4000 is - and always has been - one step ahead of the future: the first rail engine in its class with EU Stage IIIB certification in 2012 – and now EU-Stage V ready.
The Series 4000 is our masterpiece for the locomotive and railcar trainset segment. This engine provides clean power and pure profitability in all conditions.
The mtu Series 4000 has proven itself thousands of times and like its predecessors, the latest edition is a force to be reckoned with. Working for you. And for the environment.
mtu key technologies for the
reduction of emissions and consumption.
Exhaust Gas Recirculation (EGR)
Exhaust Gas Recirculation can reduce nitrogen oxide generation within the cylinder by 40 percent and more. mtu has designed a solution for compact integration of all EGR components into the PowerPack so that virtually no additional space is required. This enables customers to upgrade their railcars for compliance with the new emissions standards at no great expenditure.
Two-Stage Turbocharging
Turbocharging enables mtu engines to achieve low fuel consumption and high power output across a wide speed range. Turbochargers are finely adjusted to suit the demands on the engine in terms of cost-effectiveness, performance, dynamic response and service life. Space-saving integration of turbochargers into the engine brings the customer the added benefits of compact railcar design.
Enhanced common rail injection
mtu has been using common rail systems successfully for over 20 years now. Our mtu systems capability means we are able to exploit potential during the combustion process to help make engines especially clean and economical.
Diesel Particulate Filter (DPF)
mtu Diesel Particulate Filters are capable of lowering soot emissions to levels that in some cases are well below the statutory limits. Statutory limits form part of the emissions concept.
